This short article describes flow parameters, numerical method, andanimations of the fluid dynamics video "LES of an Inclined Jet into aSupersonic Turbulent Crossflow"(http://ecommons.library.cornell.edu/bitstream/1813/14073/3/GFM-2009.mpg[high-resolution] andhttp://ecommons.library.cornell.edu/bitstream/1813/14073/2/GFM-2009-web.m1v[low-resolution] video). We performed large-eddy simulation with the sub-gridscale (LES-SGS) stretched-vortex model of momentum and scalar transport tostudy the gas-dynamics interactions of a helium inclined round jet into asupersonic ($M=3.6$) turbulent (\Reth$ =13\times10^3$) air flow over a flatsurface. The video shows the temporal development of Mach-number and magnitudeof density-gradient in the mid-span plane, and isosurface of heliummass-fraction and $\lam_2$ (vortical structures). The identified vorticalstructures are sheets, tilted tubes, and discontinuous rings. The vorticalstructures are shown to be well correlated in space and time with heliummass-fraction isosurface ($Y_{\rm He}=0.25$).
